This study, sponsored by the National Institutes of Health and the Tuberculosis Research Centre in Chennai, India, will examine how helminth and filarial infections affect the immune respo...
The purpose of this study is to evaluate the value of Quantiferon-TB Gold (QFT-G) assay in the screening for latent tuberculosis infection (LTBI) in rheumatologic patients due to start or ...
The objective of this study is to assess the efficacy of the two current TB (tuberculosis) blood tests (Interferon Gamma Release Assays (IGRA)) compared with the standard skin test (Mantou...
Most of internationally adopted children (IAC) come from countries in which tuberculosis (TB) is endemic. Interpretation of discordant Tuberculin Skin Test (TST) and Quantiferon-Gold In Tube (QFT) res...
To make an informed viewpoint on the usefulness of Tuberculin Skin test (TST) compared to Interferon Gamma Release Assays (IGRAs) for diagnosis of Latent TB Infection (LTBI) in different geographical ...
C-Tb, an ESAT-6/CFP-10-based skin test, has similar sensitivity for active TB compared to tuberculin skin test (TST) and QuantiFERON-TB-Gold-In-Tube (QFT). However, data are limited in children and HI...
To compare tuberculin skin test (TST) and interferon gamma release assay (IGRA) in the screening of LTBI among patients with inflammatory bowel disease (IBD) in an endemic area for tuberculosis, to ev...
To assess the likelihood of detecting latent tuberculosis infection (LTBI) by the positive conversion of a serial tuberculin skin test (TST) at 1 year in inflammatory bowel disease (IBD) patients with...
A protein extracted from boiled culture of tubercle bacilli (MYCOBACTERIUM TUBERCULOSIS). It is used in the tuberculin skin test (TUBERCULIN TEST) for the diagnosis of tuberculosis infection in asymptomatic persons.
A work that reports on the results of a clinical study in which participants may receive diagnostic, therapeutic, or other types of interventions, but the investigator does not assign participants to specific interventions (as in an interventional study).
One of several skin tests to determine past or present tuberculosis infection. A purified protein derivative of the tubercle bacilli, called tuberculin, is introduced into the skin by scratch, puncture, or interdermal injection.
Works about clinical studies in which participants may receive diagnostic, therapeutic, or other types of interventions, but the investigator does not assign participants to specific interventions (as in an interventional study).
